Interfaces for most common exceptions.

Details

ThrowableInterface - The base of all exception interfaces. Declares all the same methods as Exception in a compatible way, and additionally extends StringableInterface.
BadSubjectExceptionInterface - Base interface for all exceptions that are related to some value being invalid, malformed, out of range, etc. Exposes that value via getSubject().
InvalidArgumentExceptionInterface - Allows de-coupling from the vanilla InvalidArgumentException, and makes it more useful besides signalling the problem type by exposing the argument via BadSubjectExceptionInterface#getSubejct().
ArgumentCodeAwareInterface - Useful with InvalidArgumentExceptionInterface for providing information about the source of the problematic argument.
OutOfBoundsExceptionInterface - Complementing the native OutOfBoundsException, it occurs when a key is addressed in a set that does not have it, like accessing a non-existing array key. Exposes the bad key.
OutOfRangeExceptionInterface - Complementing the native OutOfRangeException, it occurs when a value is valid but illegal, i.e. is outside of the allowed range, like when an integer that represents a colour and must be 0-255 has the value of 256. Exposes the bad value.
RuntimeExceptionInterface - A generic runtime problem.
InternalExceptionInterface - A problem that occurs in relation to the inner workings of the unit, and is not caused by the consumer. Guarantees to expose an inner exception.
